Why does my Philips set go to standby automatically?

Please note that this set has an auto-standby feature which will switch the set to stand-by mode once you pause/stop playback for about 10-15 mins. You can perform the auto-resume function to resume from the point you stopped/paused playback by following the below instructions: If your set goes to auto-standby and you want to resume from the same disc, you can just turn the set back on. The set is able to resume playback of the last 5 discs, even if the disc was ejected (open) or the set was switched to standby mode. Note: * If you want to play from the beginning, press [PREV] on the remote control when the message appears on the TV screen * Auto resume is active for DVD, VCD, SVCD and CD types of discs * USB playback DOES NOT** support this auto-resume function, so please ensure that stopping/pausing USB playback does not extend for more than 10 mins
